MODE 0F PRODUCING OBJECTS OF METAL ORNAMENTED WITH INCRUSTATIONS 0FCELLULOID, RUBBER, HORN, PEARL, AND THE LIKE ON THEIR SURFACES.

SPECIFICATION forming part of Letters Patent No. 233,076, dated October12, 1880.

Application filed Norcmber 13, 1879. Patented in Belgium November 3,1879, in Germany March 4, 1879,

and in France September 22, 1875.

To all whom it may concern Be it known that I, Orro VON OoRvIN, ofWashington, District of Columbia, have invented a new and Improved Modeof Producing Objects of Metal ornamented with Incrustations ofCelluloid, Rubber, Horn, Pearl, and the like on their surface, of whichthe following is a specification.

My proceeding will be best explained by describing how I make, forinstance, a metal table-top ornamented with incrustations either ofanother metal, mother-of-pearl, shell, glass, porcelain, enamel, stonesof any kind, jet, amber, ivory, tortoise-shell, or any substitute orimitation of these or similar materials, whether made of india-rubber,gutta-percha, celluloid, or other material.

On a copper plate or any other metallized surface I trace the outlinesof the pattern which is to be formed by incrustations or inlaid work.The pieces to be incrusted, consisting of any of the materials beforereferred to,are shaped by cutting, stamping, filing, sawing, or in anyother suitable manner, according to the position and space they areseverally to occupy in the design. This done, that surface of each piecewhich is intended to appear in the finished work is pasted, by means ofvarnish or other appropriate adhesive stuff, to the bed-plate, on whichthe pattern has already been outlined, each, of course, in that placewhich it is to occupy in the design. The surface of this plate formingthe base, 011 which the pieces to be incrusted are now pasted, and ofwhich the back is to be seen, is now prepared in the manner known toevery galvanoplast,so as to secure a metallic deposit on the pieces.When the plate is thusprepared itis immersed in a solution of sulphateof copper, or whatever other appropriate metallic solution is desired,and, after being attached to the positive pole of a galvanic battery,the metal contained in the solution will be deposited and spread overthe whole prepared plate, and cover and envelop all the pasted pieces.

When the metallic deposit has acquired the desired thickness it isdetached from the baseplate, the varnish or glue easily giving way,

a table-top may now be still more ornamented 5 by engraving, gilding,silver-plating, or in any manner desired.

Letters Patent for this my invention have been granted to me already inFrance, Germany, and Belgium.

By like process may be made tablets, panels for rooms, furniture, 860.,covers of albums or books, boxes, $50., and articles of any shape andkind and now,

Having described and illustrated the tical application of my invention,so as to enable any person skilled in the art to use the same, I claimas my invention and discovery 1. The process of pasting or sticking ofthe several pieces intended for the incrustation, inlaying, orornamentation of the surface of the article to be produced, by theirobverse face, upon a base,bed,or ground plate, superficially the reverseof the surface to be ornamented, in the manner above indicated, or anyequivalent manner, substantially as and for the purpose above described.

2. The process of metallizin g the reverse, the back, and edges of thepieces to be inlaid, in-

prac- 6 5 crusted upon, or sunken into the surface of So the article heproduced, substantially as and for the purpose above described, or sothat a galvanic deposit of any desired metal may be made thereonclosely, minutely, and perfectly adherent thereto, thereby forming,tachment of the bed-plate, the obverse face of such article with aperfect surface, inlaid, incrusted, or ornamented, as desired.

3. The process for production of metallic objects with incrustations onthe surface, substantially as above described.
